This year, Jenny Hirt's 4-year-old daughter Caroline wore the adorable yellow-and-purple dress on her first day of school, making her the 18th of 19 girls to wear the frock. Caroline's older sister, Ally, was the 17th, and Caroline's cousin Sylvia was the 19th. Hirt was actually the fifth girl to wear the dress.

While the style does look a bit dated, the history behind the dress make the act of wearing it so much more special. Hirt says her grandmother and great-grandmother made the dress in 1950 for her aunt, Martha Esch, to wear to kindergarten in 1950. Since then, every girl in the family has carried on the tradition of donning the dress on the first day of school.

So far, the dress has been worn in seven different states, including Colorado (where Hirt and her family live) and Michigan (where Martha Esch wore the dress). To this day, nearly 67 years later, no one has had to make any major alterations to the dress; it remains in good condition.

"It's a big big deal to my mom as it was her mom who helped make the dress," Hirt told TODAY.com. Her mom, Katy Pearce, even flew from Colorado to South Carolina when Ally, Hirt's daughter and Pearce's granddaughter, wore the smock.

How sweet! It's so nice to see people embracing their roots and keeping old family traditions alive. Hirt told Huffington Post that there are at least three more girls — ages 2, 3, and 4 — who are waiting in the wings for their time to shine in the dress.

“It is a way to carry on the memories of family members, try to instill pride of tradition in our kids and bind us together as a family,” she said. “It’s a big deal to us.”
